I am an Associate Professor of Linguistics at the University of Wisconsin-Milwaukee. I am broadly interested in language acquisition, focusing on what language learners know about the sound structure of the target language, and how various factors interact with the acquisition of this knowledge. To study these, I use converging evidence from several sources including experimental speech production data and longitudinal speech corpora, and ultrasound recordings of tongue movements during the articulation of speech sounds.
I did my undergraduate studies at Korea University in Seoul, and earned my Ph.D. at the Department of Cognitive, Linguistic & Psychological Sciences at Brown University. I did my postdoctoral training with Dr. Katherine Demuth at Brown University (now at Macquarie University) and Dr. Stefanie Shattuck-Hufnagel at MIT, who both greatly influenced my research.
